A known golf blog stated that the industry was surprised by the Kirkland Signature Golf Balls when Costco introduced them in 2016. These golf balls have been named K-Sig and you could originally get 24 of them for $30, a lot cheaper compared to big brands. What’s more, the Kirkland golf balls perform better than Pro V1 golf balls. Therefore, it is no surprise that Costco’s golf balls have taken the golf world by storm.
